Several years ago I ordered a new seat belt for my Wrangler and ended up not needing it. Here it sits, still in factory packaging. If you need it, it's yours.
It's a front (3 point) belt will all mounting hardware included.
Rather than go into full detail, it is this...
Beams Industries SCH3241000 - 3 Point Retractable Lap & Shoulder Harness with Push-Button Buckle - Quadratec
By the time S&H is included you'll spend close to $90, here's the exact same thing, brand new, for less than half that.
$40 obo. I'm not terribly savvy at selling over the internet. I'd prefer $$$ or money order, but I'm flexible. Add $5 if I need to ship it. Call or text 570-236-3830
